Predefined Constants

By default Libevent turns underlying file descriptors, or sockets, to
non-blocking mode. This flag tells to leave them non-blocking.

EventListener::OPT_CLOSE_ON_FREE

If this option is set, the connection listener closes its underlying
socket when the
EventListener
object is freed.

EventListener::OPT_CLOSE_ON_EXEC

If this option is set, the connection listener sets the close-on-exec
flag on the underlying listener socket. See platform documentation for
fcntl
and
FD_CLOEXEC
for more information.

EventListener::OPT_REUSEABLE

By default on some platforms, once a listener socket is closed, no
other socket can bind to the same port until a while has passed.
Setting this option makes Libevent mark the socket as reusable, so that
once it is closed, another socket can be opened to listen on the same
port.

EventListener::OPT_THREADSAFE

Allocate locks for the listener, so that it’s safe to use it from
multiple threads.
